During his week-long visit to Ukraine, Professor Iosevich (University of Rochester) will deliver two series of lectures:

Discrete Fourier transform, uncertainty principle, and signal recovery

Lviv, 23-24 September

and

Restriction theory, uncertainty principles, and annihilating pairs

Kyiv, 26-27 September

Welcome everyone! Understanding the lectures requires knowledge of the basics of mathematical analysis and the Fourier transform. The series of lectures in Kyiv and Lviv will be independent of each other, participants in Kyiv are not expected to have previously attended lectures in Lviv.

Alex Iosevich is an LMS Distinguished Visiting Fellow at ICMU. Professor Iosevich is a world leading expert in harmonic analysis who has made important contributions to both continuous and desecrete Fourier analysis. Alex Iosevich spent his childhood in Lviv. He studied at the University of Chicago, in 1993 he defended his PhD thesis at the University of California, Los Angeles. Since 2010, Alex has been a professor at the University of Rochester in New York. His research interests include harmonic analysis and geometric measure theory, data science and neural networks, analytic number theory, and discrete geometry. Professor Iosevich is an excellent teacher and mentor, he is constantly engaged in research projects with students. More than 20 PhD candidates wrote theses under his guidance.

The Ukrainian host is Rostyslav Hryniv, professor at the Ukrainian Catholic University.

Advertisement: in the summer 2025 professor Iosevich and his colleagues are going to run a summer workshop on signal recovery: see StemForAll 2025. Similar workshops could be also run in other places under the guidance of the organisers. Volunteers to run a similar workshop may contact professor Iosevich.
